bah-basic machines, you guys ought to get a load of dales cnc machine. it can cut anything.
bus and car moulds, rubber oc seats. normal surfboards and pre cut pvc foam planks on suction caps. full block foam on a roughly 5 x2 m table. does a full 12'6 board easy.
the bus moulds are cut in a series of foam slabs, glued together, a bit of sanding and bang, there's your back end of a bus ready to be glassed
longer boards the joints a perfect. thats how he can tint really longer two piece foam planks boards. other machines leave you with big gaps and lots of expanding foam fill
the thing can open up the tooling box, put away tooling bit away, then pickup another one.
i never get bored watching it - truly amazing.
aku's are very good
